Microvent Vents for LED are proven to reduce condensation and contaminants in LED
The problem: Lighting enclosures exposed to temperature and pressure changes.
Changing temperatures, dust, dirt, and moisture considerably impact the electronics of outdoor lights. Rain, for example, can cool down a lighting enclosure dramatically, causing a vacuum of 200 mbar (3psi) or more inside the enclosure. To equalize the pressure, air and moisture are drawn through the seal into the enclosure where the moisture condenses on the cooler inner walls. This can considerably impair performance.
Outside LED are vulnerable to a range of climate, road, and environmental challenges. Dust, debris, fluids and condensation can ultimately compromise led performance, aesthetics, and/or safety. led designs employing open torturous/labyrinth paths or open tubes are a partial solution. However, they can’t solve all the challenges of performance-damaging environmental contaminants.
The solution: Equalize pressure by continuous venting.
Microvent® Protective Vents protect against the negative effects of pressure differentials caused by temperature changes. With their integrated Microvent™ Membrane, these vents allow an enclosure to equalize pressure quickly when subjected to changes in temperature and pressure. These vents also provide an effective barrier against harsh weather conditions (e.g., rain, snow, high winds), while allowing water vapor to exit quickly and reduce the likelihood of condensation on the lens.
Patented Microvent® Automotive Vents forLED are proven to reduce condensation and contaminants in headlamp assemblies by:
- allowing rapid exchange of air in response to pressure/temperature changes
- driving moisture out of the headlamp by diffusion through a microporous ePTFE membrane structure
- providing a reliable, long-lasting barrier to water and automotive fluids
- blocking entry of dust and other particulates to the lens and housing
